SEPA not working when PayOne Plugin active

Hey,

I would like to activate novalnet and payone at the same time. For Payone I’m using this plugin: https://www.sellxed.com/shop/de/wordpress-woocommerce-payone-zahlungs-plugin.html

And your’s for Novalnet. When I activate the SEPA payment method then when on the checkout page the payment methods are loading (ajax loading), and they finally loaded then I got this result: https://postimg.org/image/hl85spos5/

So instead of showing the payment methods it shows this javascript code.
Could you please fix that? It’s working when I enable another Novalnet Payment method but not with SEPA.

Just a short note: it’s got nothing to do with the selected theme, I installed the standard twenty sixteen theme to test this case and it’s not working even when it’s enabled (as you can see in the screenshot).

Thank you for your help
